Forto Coffee Shot has more caffeine than Red Bull on both counts: 225mg per 2 oz shot against 80mg per 8.4 oz can, and about 112mg per fluid ounce against 10. The serving sizes differ, so the table below shows both ways of counting.
These are different categories of drink, which changes how the caffeine arrives. Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.
Forto Coffee Shot vs Red Bull: the numbers
| Forto Coffee Shot | Red Bull | |
|---|---|---|
| Caffeine per serving | 225mg per 2 oz shot | 80mg per 8.4 oz can |
| Caffeine per fl oz | 112.5mg | 9.5mg |
| Servings to reach 400mg (FDA context) | 1.8 | 5.0 |
Sources: Forto Coffee Shot's figure is verified in our Forto Coffee Shot caffeine guide against Caffeine Informer (source); Red Bull's figure is verified in our Red Bull guide against Red Bull label / Caffeine Informer (source).
The concentration gap is the striking part: Forto Coffee Shot packs roughly 12 times the caffeine per ounce. Sipping speed matters at that density; a 2 oz shot finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick Red Bull when you want the lighter dose or a slower ramp, and Forto Coffee Shot when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
